Was just randomly thinking about little things or ideas that, when you think about it, are genius.
My first one; when buying cards, those that have printed on the back, which size stamp they'll need.
Second; the little tapes on the back of some nappy pants, so you can still roll the nappy up tight, even without the side tapes.
Third; rash vests and good length swim shorts for girls. Amazing for my fair skinned DD to run and play in the garden, rather than a swimming costume. Doesn't matter if she gets soaked, stops some of the sunscreen worries and doesn't give her a hungry bum (wedgie). Saw how comfortable her little brother was in the combo, and she's not looked back!
Any other genius level (tongue in cheek) ideas you'd care to share?
